64-bit<br />
This item indicates if the CPU installed in Socket 1 or Socket 2 supports 64-bit<br />
technology.<br />
Clock Spread Spectrum<br />
Select Enable to enable Clock Spectrum support, which will allow the BIOS to monitor<br />
and attempt to reduce the level of Electromagnetic Interference caused by the<br />
components whenever needed. The options are Disabled and Enabled.<br />
RTID (Record Types IDs)<br />
This feature displays the total number of Record Type IDs for local and remote<br />
pools. The options are Optimal and Alternate.<br />
Hyper-threading<br />
Select Enabled to support Intel Hyper-threading Technology to enhance CPU performance.<br />
The options are Enabled and Disabled.<br />
Active Processor Cores<br />
Set to Enabled to use a processor's second core and above. (Please refer to Intel's<br />
website for more information.) The options are All, 1 and 2.<br />
Limit CPUID Maximum<br />
Use this feature to set the maximum CPU ID value. Enable this function to boot<br />
the legacy operating systems that cannot support processors with extended CPUID<br />
functions. The options are Enabled and Disabled (for the Windows OS).<br />
Execute-Disable Bit Capability (Available if supported by the OS & the CPU)<br />
Select Enabled to enable the Execute Disable Bit which will allow the processor<br />
to designate areas in the system memory where an application code can execute<br />
and where it cannot, thus preventing a worm or a virus from flooding illegal codes<br />
to overwhelm the processor or damage the system during an attack. The default is<br />
Enabled. (Refer to Intel and Microsoft Web sites for more information.)<br />
Intel® AES-NI<br />
Select Enable to use the Intel Advanced Encryption Standard (AES) New Instructions<br />
